Whispering Gallery Modes in Hollow Microcavities Loaded with Semiconductor Quantum Dots

We present our recent results on development and characterization of hollow poly(methyl methacrylate) (PMMA) microspheres loaded with CdSe/CdS core-shell quantum dots. The PMMA microspheres were fabricated using the spray-drying method and investigated using scanning electron microscopy, confocal mi...

Summary:We present our recent results on development and characterization of hollow poly(methyl methacrylate) (PMMA) microspheres loaded with CdSe/CdS core-shell quantum dots. The PMMA microspheres were fabricated using the spray-drying method and investigated using scanning electron microscopy, confocal microscopy, and fluorescent lifetime imaging microscopy. Micro-photoluminescence studies of individual microsperes were also performed revealing pronounced whispering gallery modes (WGM). The results demonstrate high optical quality of the hollow microspheres and their potential application as optical microresonators.
